Nadal, looking sluggish throughout the match, was broken in the last game of the first set and then failed to win a single point in the tiebreaker.

"It was tough," the Spaniard said. "I didn't really play very well. But anyway, I am happy with my tournament."

Nadal got to the same stage here last year and went on to reach the Wimbledon final, where he lost to Roger Federer. Nadal plans to go home to Mallorca, Spain, for a few days to relax before returning for Wimbledon, which starts June 25.

Roddick held off a break point at 5-4 with a service winner to take the first set, but had to rally from 4-1 down in the second.

The American, who is aiming for his fourth title at Queen's, will face Dmitry Tursunov, who rallied from 2-4 in the final set to upset third-seeded Fernando Gonzalez 6-3, 6-7 (5), 6-4.
